Subject: No point in trying to update the -L file on loss of link if no -L has
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=f7c5cb4d4dd094fea75c036cbd622b5f698b7443;p=openbsd

No point in trying to update the -L file on loss of link if no -L has
been specified. Eliminates spurious "Couldn't write ''" log messages.

Spotted while looking into Roman Gorelov's logs on another problem.
