localrepo: don't add deleted files to list of modified/added files (
issue2761)
If a file is deleted (rm, not 'hg rm') from the working dir
an attempt to run 'hg diff -r X', with the file being present in X will
cause an abort.
We didn't check if the file has been deleted from the working dir
and later on tried to open it to compare with the one from X, causing the abort.
This fix adds that check. Consequently, no output will be returned.
util: move checkosfilename call from path_auditor to opener
path_auditor is used for checking patterns too, but a pattern is not a valid
filename.
This patch fixes
98ee3dd5bab4, which introduced the bug:
$ hg log -l3 glob:**.py
abort: filename contains '*', which is reserved on Windows: mercurial\**.py
grep: don't print data from binary files for matches (
