tests: handle differences between missing file error strings on Windows and Unix

run-tests: don't warn on unnecessary globs mandated by check-code.py When test output is processed, if os.altsep is defined (i.e. on Windows), TTest.globmatch() will cause a warning later on if a line has a glob that isn't necessary. Unfortunately, the regex checking in check-code.py doesn't have this context. Therefore we ended up with cases where the test would get flagged with a warning only on Windows because a glob was present, because check-code.py would warn if it wasn't. For example, from test-subrepo.t: $ hg -R issue1852a push `pwd`/issue1852c pushing to $TESTTMP/issue1852c (glob) The glob isn't necessary here because the slash is shown as it was provided. However, check-code mandates one to handle the case where the default path has backslashes in it. Break the cycle by checking against a subset of the check-code rules before flagging the test with a warning, and ignore the superfluous glob if it matches a rule. This change fixes warnings in test-largefiles-update.t, test-subrepo.t, test-tag.t, and test-rename-dir-merge.t on Windows. I really hate that the rules are copy/pasted here (minus the leading two spaces) because it would be nice to only update the rules once, in a single place. But I'm not sure how else to do it. I'm open to suggestions. Splitting some of the rules out of check-code.py seems wrong, but so does moving check-code.py out of contrib, given that other checking scripts live there. There are other glob patterns that could be copied over, but this is enough to make the current tests run on Windows.

update: remove unnecessary check for unknown files with --check As far as I and the test suite can tell, the checks in manifestmerge() already report the errors (whether or not --check is given), so we don't need to call merge.checkunknown(). Since this is the last call to the method, also remove the method.

tests: move a multi-statement debuglocks hook into a shell script for Windows Before this patch, a part of "test-push-hook-lock.t" fails unexpectedly on Windows environment, because semicolon (";") isn't recognized as the command separator by "cmd.exe". This is fixed the same way as a similar issue in 7c253c23de3b.

tests: fix globs for Windows test-largefiles-update.t, test-subrepo.t, test-tag.t, and test-rename-dir-merge.t still warn about no result returned because of unnecessary globs that test-check-code-hg.t wants, relating to output for pushing to, pulling from and moving X to Y.

run-tests: include quotes in the HGEDITOR value when storing sys.executable This fixes test-install.t on Windows that broke in 2122b82b6987 when shlex.split() was added to the debuginstall command: @@ -7,8 +7,11 @@ checking installed modules (*mercurial)... (glob) checking templates (*mercurial?templates)... (glob) checking commit editor... + Can't find editor 'c:\Python27\python.exe -c "(omitted)"' in PATH + (specify a commit editor in your configuration file) checking username... - no problems detected + 1 problems detected, please check your install! + [1] What happens is that shlex.split() on Windows turns this: c:\Python27\python.exe -c "import sys; sys.exit(0)" into this: ['c:Python27python.exe', '-c', 'import sys; sys.exit(0)'] While technically a regression, most programs on Windows live in some flavor of 'Program Files', and therefore the environment variable needs to contain quotes anyway to handle the space. This wasn't handled prior to the shlex() change, because it tested the whole environment variable to see if it was an executable, or split on the first space and tested again.

mq: when adding headers in plain mode, separate them from message (issue4453) c87f2a5a6e49 did a clean-up in one direction ... but we want it in the other direction.

mq: introduce insertplainheader - same naive implementation as before

mq: when setting message in plain mode, separate it from header (issue4453) Fix inconsistent handling of plain header separation in mq patcheader - and contrary to c87f2a5a6e49, do it in the direction of having an empty line between header and description. Plain patches are like mails and should thus have an empty line between headers and body in compliance with RFC 822 3.1.
