Subject: Remove a redundant while-loop condition when reading RFC822-style
X-Git-Url: https://git.distorted.org.uk/u/mdw/putty/commitdiff_plain/1ea566c3e96413d7edb40c50b0f7c7f8a5536079

Remove a redundant while-loop condition when reading RFC822-style
header text from a PuTTY key file.

(It's silly to have both while (len > 0) at the top of the loop _and_
an if (len == 0) return in the middle, and in fact the former was the
erroneous one since it would have prohibited a 39-character header,
which I intended to be permitted.)
