You will find kernel documentation [1] on preferred email clients and
formats of interest.
Among other things, the advise on the format of email messages is:
Don't send patches with ``format=flowed``.  This can cause unexpected
and unwanted line breaks.

My personal preference is the use of 'git send-email'. I've also found
mutt to be compliant with the guidelines laid out in the reference
doc.
Hope this helps.
