fast-import should not use strncmp_icase. When it does, files with
similar names, but different case can be lost in the import. For
example...
M 100644 :1 FileName.txt
D Filename.txt
...would end up deleting FileName from the index during the fast-
import when strncmp_icase is used and core.ignorecase=true. The
intent in the above snippet is to rename the file, not delete it.
Replacing strncmp_icase with strncmp in fast-import.c fixes the
issue.
alternatives:
* check if the filesystem is case-preserving. If it is, don't
set core.ignorecase=true. This, however, exposes another issue
where git is tricked by stat into thinking that tracked files
are untracked on case-preserving and case-insensitive filesystems.
