dirstate: avoid normalizing letter case on icasefs for exact match (issue3340)
on icasefs, "hg qnew" fails to import changing letter case of filename
already occurred in working directory, for example:
$ hg rename a tmp
$ hg rename tmp A
$ hg qnew casechange
$ hg status
R a
$
"hg qnew" invokes 'dirstate.walk()' via 'localrepository.commit()'
with 'exact match' matching object having exact filenames of targets
in ones 'files()'.
current implementation of 'dirstate.walk()' always normalizes letter
case of filenames from 'match.files()' on icasefs, even though exact
matching is required.
then, files only different in letter case are treated as one file.
this patch prevents 'dirstate.walk()' from normalizing, if exact
matching is required, even on icasefs.
filenames for 'exact matching' are given not from user command line,
but from dirstate walk result, manifest of changecontext, patch files
or fixed list for specific system files (e.g.: '.hgtags').
in such case, case normalization should not be done, so this patch
works well.

hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
update the current patch
If any file patterns are provided, the refreshed patch will contain only
the modifications that match those patterns; the remaining modifications
will remain in the working directory.
If -s/--short is specified, files currently included in the patch will be
refreshed just like matched files and remain in the patch.
If -e/--edit is specified, Mercurial will start your configured editor for
you to enter a message. In case qrefresh fails, you will find a backup of
your message in ".hg/last-message.txt".
hg add/remove/copy/rename work as usual, though you might want to use git-
style patches (-g/--git or [diff] git=1) to track copies and renames. See
the diffs help topic for more information on the git diff format.
Returns 0 on success.
options:
-e --edit edit commit message
-g --git use git extended diff format
-s --short refresh only files already in the patch and
specified files
