[PATCH] guilt: skip empty line after from: line in patch descriptoin

[Theodore Ts'o <tytso@mit.edu>]

Commit 2cc8d353d7ecb broke manually written patch descriptions of the
form:

    > Frobnozzle: this is a patch subject
    >
    > From: Fred McNurk <fred@mcnurt.foo>
    >
    > This is the patch description

Commit 8f88f953580a0 partially fixed things by filtering out the From:
field, but it did not filter out the empty line (if present) after the
From: field, so it resulted in commit bodies which looked like this:

    > Frobnozzle: this is a patch subject
    >
    >
    > This is the patch description

instead of

    > Frobnozzle: this is a patch subject
    >
    > This is the patch description

The ext4 patch queue has used this format for years, and this change
should not break other patches which look like mail headers and
bodies.
