help: search section of help topic by translated section name correctly
Before this patch, "hg help topic.section" might show unexpected
section of help topic in some encoding.
It applies str.lower() instead of encoding.lower(str) on translated
message to search section case-insensitively, but some encoding uses
0x41(A) - 0x5a(Z) as the second or later byte of multi-byte character
(for example, ja_JP.cp932), and str.lower() causes unexpected result.
To search section of help topic by translated section name correctly,
this patch replaces str.lower() by encoding.lower(str) for both query
string (in commands.help()) and translated help text (in
minirst.getsections()).

$ cd "`dirname "$TESTDIR"`"
look for python scripts without the execute bit
$ hg files 'set:**.py and not exec() and grep(r"^#!.*?python")'

look for python scripts with execute bit but not shebang
