[hackers] [sbase] [PATCH 1/3] ed: Don't match against line 0 in search()

From: Wolfgang Corcoran-Mathe <wcm_AT_sigwinch.xyz>
Date: Sun, 24 Jul 2016 21:04:27 -0400

regexec(3) happily matches /^$/ against the text of line
zero (the null string), causing an error.

Also update email address for Wolfgang Corcoran-Mathe
