tests: remove protected file forcibly for portability Before this patch, test-command-template.t is timed out on Solaris, because "rm" on permission denied file implies prompting "override protection 0 (yes/no)?" and blocks execution of test script.

tests: dump journal file by python script instead of sed for portability Before this patch, test-repair-strip.t fails on Solaris, because of "sed" on it doesn't work as expected if input contains null ('\0') character.

tests: execute check-config.py without xargs Before this patch, test-check-config.t fails on Solaris, because "xargs" doesn't invoke check-config.py with all filenames at once. "xargs" may invoke specified command multiple times with part of arguments given from stdin: according to "xargs(1)" man page, this dividing arguments is system-dependent. For portability of test-check-config.t, this patch adds "xargs" like mode to check-config.py and executes it in test-check-config.t without "xargs".

tests: avoid nested quoting on command line for portability Before this patch, test-revset.t fails on Solaris using ksh as default "sh", because nested quoting below isn't acceptable for it. +-----------------------------+ inner quoting "`python -c "print '|'.join(['0:1'] * 500)"`" +-------------------------------------------+ outer quoting This patch does below for portability. - omit outer quoting This should be safe, because generated string contains no white space character. - use '+' instead of '|' (for safety) '|' has special meaning for many shell, but '+' isn't (at least, for ordinary ones).

version: verbose list internal and external extension source (issue4731)

check-code: allow "grep pattern filename-containing-dash-a" We're trying to forbid "grep -a" and unintentionally complained even if the "-a" was part of the filename. Requiring a space before "-a" to match is probably good enough.

rebase: update working directory when aborting (issue5084)

revset: flatten chained 'list' operations (aka function args) (issue5072) Internal _matchfiles() function can take bunch of arguments, which would lead to a maximum recursion depth error. This patch avoids the excessive stack use by flattening 'list' nodes beforehand. Since getlist() no longer takes a nested 'list' nodes, _parsealiasdecl() also needs to flatten argument list, "aliasname($1, $2, ...)".

help: fix typo in backgroundclose documentation

revert: makes interactive mode ask to forget added files (issue4936) Before this patch revert interactive mode unconditionally forgets added files. This patch fixes this by asking user if he wants to forget added file. If user doesn't want to forget given file, it is added to matcher_opts exclude list, to not reviewing it later with other modified files.
