annotate src/fetch.c @ 58:b4e6f7f96135 noffle

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
[svn] Add some intermediate variables for easier debugging in needsMark(). It seems that thread mode is sometimes not working. Changed some variable types and used some casts to avoid compiler warnings about signedness. In general, int should be used for parameters for allowing a signedness assertion in the function.
