annotate lwasm/lwasm.c @ 354:433851a26794

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make base prefix sigils error out if no number following Prefix sigils (0x, %, &, @, $) were parsing to 0 if there was no number following the prefix. Make parsing fail if that is the case. Note that in a couple of obscure cases, it may give "undefined symbol" rather than "bad operand" due to some interactions with other unfortunate features of the source format.
