[PATCH v2 0/7] Cure some format-patch wrapping and encoding issues

Hi all.

[This is the second version of this series. If you still remember the first version, you might want to jump directly to the summary of changes below.]

The main point of this series is to teach git to encode my name correctly, see patches 5+6, so that the decoded version is actually my name, so that send-email does not insist on adding a wrong superfluous From: line to the mail body.

The other patches more mostly by-products that fix other issues I came across.

Patch 1 fixes an old off-by-one error, so that wrapped text may now use all available columns.

Patches 2 and 3 make the wrapping of header lines more correct, i. e., neither too early nor too late.

Patch 4 does some refactoring, which is too unrelated to be included in one of the later patches.

Patch 5 improves RFC 2047 encoding; patch 6 removes an old non-RFC conform workaround.

Patch 7 is more an RFC, which seems to be a good idea from my point of view. Indeed, I thought the current implementation is erroneous, until Junio C Hamano pointed out, that this might be desired behavior. Thus, make up your mind about this one.

The series is currently based on the maint branch, but it applies to master as well. It does also apply to next, but then my implementation of isprint() has to be dropped from patch 5.

Changes in v2:
- patch 1 is new and is a result of the v1 discussion
- patch 5+6 split the old patch 4 into two patches
- use of constants for maximum line lengths
- even better adherence to RFC 2047 than v1
- updated commit messages/comments

Regards Jan
