annotate lib/lib.h @ 64:67ee3a0b76e1

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
In bunzip replace setjmp/longjmp handling with error_exit(), replace string based handling of a 6-byte header with with two 24-bit integer reads. Use xmalloc() and xzalloc().
