[PATCH] infcmd.c (attach_command): Improve comment.

[Doug Evans]

Hi.

I always have to re-lookup what target_attach_no_wait means,
and what targets set it to non-zero, every time I look at this code.

This patch is a modest attempt at clearing things up for me.
[maybe a good example of why double negatives should be avoided,
in this case "! no-wait".  maybe not.]
