annotate lwasm/lwasm.c @ 533:543b5d1341d2

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add note to manual about numeric entry addresses in scripts Link scripts require a numeric entry address to begin with a digit. Make a note about that in the manual since hex addresses starting with letters could be mistaken for symbols.
