current lfconvert implementation uses combination of "ui.config()" and
"str.split(' ')" to get largefiles.patterns configuration.
but it can not handle multiline configuration in hgrc files correctly.
lfconvert should use "ui.configlist()" instead of it, as same as
override_add does.
This gets us very close to full test coverage of lfconvert. The only
features not tested are:
- .hgtags conversion
- abort when largefile becomes symlink
- instead of converting a single changeset with a single file, convert
two changesets which each add a mix of normal and large files
- make one of the large files not-so-large, but identified as large
by filename
- use shorter, simpler filenames
- put some files in a subdirectory
- test that file contents are correctly converted
- drop unnecessary cleanup step
test-largefiles.t is getting pretty big, and there's lots more to test
in lfconvert. And lfconvert is a fairly orthogonal feature to the
rest of largefiles.
Globbing is usually used for filenames, so on windows it is reasonable and very
convenient that glob patterns accepts '\' or '/' when the pattern specifies
'/'.
