Hi Workers!

It seems, that CTRL-G doesn't work perfectly with fsdb. I realized this
debugging perl, and wanted to jump to a symbol called _Perl_comppad.
However fsdb jumped to _Perl_comppad_name. It happens because the
binary search in debug/common/syms.c doesn't check the full name of
the symbol, but returns the first partial match. Below is a patch that
solves this problem for me (I hope it won't break something else).
