fixed typos found in translatable strings This is from a spell-check of hg.pot.

graphlog, win32mbcs: capitalize ASCII

highlight: consistently capitalize Pygments

win32mbcs: capitalize Unicode

commands: expand "arg" -> "argument" in showconfig help strings It is easier to translate full sentences without abbreviations, or said differently, I don't know a short Danish word for "argument".

wrap string literals in error messages

convert/gnuarch: wrap long line, format kwargs without spaces

convert/cvsps: wrap long lines

convert/subversion: wrap long lines in comments

test-hybridencode: break long string literals

revlog: make triple-quoted string a real comment

posix: do not use fstat in isowner The fstat function was undefined, but never used since a stat object was always passed in the optional st argument. Passing st is now mandatory. This bug crept in when util was split up into posix and windows modules. The fstat function is still defined in util, but importing it into posix would create an import cycle which seems unnecessary.

removed unused imports

Move alias into core

mq: rename setheader to updateheader and fix comment
