Subject: makedepend.SH: Split too long lines; properly join
X-Git-Tag: v5.21.6~483

makedepend.SH: Split too long lines; properly join

I had thought that a continuation introduced a space.  But no,
a continuation can happen in the middle of a token.

And this splits lines that are getting very long to avoid preprocessor
limitations.
