commit a1f6baa5 (wrap long header lines) breaks my habit

Hello,

for rebasing I'm using normally

   git format-patch -k --stdout a..b | git am -k -3

With commit

  commit a1f6baa5c97abc8b579fa7ac7c4dc21971bdc048
  format-patch: wrap long header lines 
  (since >v1.7.4)

this isn't possible anymore for those patches which have more then 78 characters on the first line.

The wrapping of the lines in the commit message will not be seen when commiting but when rebasing via format-patch.

Was this the intention of this change or was my sort of workflow just not in focus?

Any suggestion?

Stefan
