yeah, no bug. RFC2047 sec 2 and section 6 say that all encoded words
shall be no longer than 75 ascii characters, the one containing
"Commit_by" is over-length.
Unusually for an RFC leniency is not reccomended,
section 6.1. clause 1
(1) Any message or body part header field defined as '*text', or any
user-defined header field, should be parsed as follows: Beginning
at the start of the field-body and immediately following each
occurrence of 'linear-white-space', each sequence of up to 75
printable characters (not containing any 'linear-white-space')
should be examined to see if it is an 'encoded-word' according to
the syntax rules in section 2. Any other sequence of printable
characters should be treated as ordinary ASCII text.
