annotate mercurial/pure/diffhelpers.py @ 19954:427ce5633c1c stable

largefiles: don't prompt for normal/largefile changes when doing plain updates We used to get like: $ hg up -r 2 foo has been turned into a normal file keep as (l)argefile or use (n)ormal file? l getting changed largefiles 0 largefiles updated, 0 removed 0 files updated, 0 files merged, 2 files removed, 0 files unresolved $ cat foo cat: foo: No such file or directory [1] - which both asked the wrong question and did the wrong thing. Instead, skip this conflict resolution when the local conflicting file has been scheduled for removal and there thus is no conflict.
