[RFC] Making format-patch output better when blank line is missing?

Hello,

I'm using git-format-patch to send commit diff emails, and it was
recently brought to my atention that if a commit message consists
entirely in a paragraph with no blank lines (particluarly, no blank line
after the first line, which is not a summary but just the first line of
the paragraph), git-format-patch will place all the commit message in
the Subject, which is inconvenient to read.

Do you think it would be good to have format-patch do something like
this in this case?:

    Subject: [PATCH] This commit introduces a new function bla() that [...]

    [...] makes it possible to apply the frobniz operation to objects
    that don't bla bla bla bla.

(I realize that, with this, the applying logic would have to learn about
it. Hm.)
