check-code: examine magic pattern matching against contents of a file Before this patch, check-code examines "magic" pattern (e.g. '^#!.*python') matching against not contents of a file, but name of it. This unintentionally omits code checking against Python source file, of which filename doesn't end with "*.py" or "*.cgi", even though contents of it starts with "#!/bin/python" or so. In this change, 'pre' refers contents of file 'f'.

docchecker: use indentation of 4 spaces This is fixing for 'must indent 4 spaces' check-code rule. check-code has overlooked this, because a file isn't recognized as one to be checked (this problem is fixed by subsequent patch).

docchecker: remove naked except clause This is fixing for 'naked except clause' check-code rule. check-code has overlooked this, because a file isn't recognized as one to be checked (this problem is fixed by subsequent patch).

misc: use modern exception syntax This is fixing for 'legacy exception syntax; use "as" instead of ","' check-code rule. check-code has overlooked these, because files aren't recognized as one to be checked (this problem is fixed by subsequent patch).

f: use modern octal number formatting This is fixing for 'legacy octal syntax; use "0o" prefix instead of "0"' check-code rule. check-code has overlooked this, because a file isn't recognized as one to be checked (this problem is fixed by subsequent patch).

hg-ssh: parenthesize non-translated message This is fixing for 'missing _() in ui message (use () to hide false-positives)' check-code rule. check-code has overlooked this, because a file isn't recognized as one to be checked (this problem is fixed by subsequent patch).

f: add whitespace around operator This is fixing for 'missing whitespace in expression' check-code rule. check-code has overlooked this, because a file isn't recognized as one to be checked (this problem is fixed by subsequent patch).

check-commit: omit whitespace This is fixing for 'no whitespace around = for named parameters' check-code rule. check-code has overlooked this, because a file isn't recognized as one to be checked (this problem is fixed by subsequent patch).

check-commit: wrap too long line This is fixing for 'line too long' check-code rule. check-code has overlooked this, because a file isn't recognized as one to be checked (this problem is fixed by subsequent patch).

setup: avoid procedure related to hg.exe at setup.py --pure Before this patch, "setup.py --pure" fails on Windows, because hgbuildscripts.run() tries to copy "hg.exe", which doesn't generated at "setup.py --pure". At that time, run_command('build_hgexe') invoked in hgbuildscripts.run() does nothing and returns successfully. Therefore, subsequent procedure assuming existence of "hg.exe" fails. This patch avoids procedure related to "hg.exe" (= all of hgbuildscripts.run() except for build_scripts.run() invocation) at "setup.py --pure".
