annotate src/imap/main.c @ 903:fd8888f6f037 HEAD

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Naming style changes, finally got tired of most of the typedefs. Also the previous enum -> macro change reverted so that we don't use the highest bit anymore, that's incompatible with old indexes so they will be rebuilt.
