| Original Comment: | Fix some remaining corner cases when having a checkout on '/'..
- update was asserting when localroot is '/' - fix file_canonical_name() so it doesn't return '.' path must be '/' and avoid the double '/' on beginning in some case. - refactor file_canonical_name() function to avoid some duplicated code. - fix file_relative_name() so it handle properly relative path when working on '/'. |

Merge again checkout_on_root_fix.
Fix more cases when working from '/', should not affect when working normally. check-in: af194dbb user: mgagnon tags: trunk | |
