Fix aerc auto line break

fix_aerc_line_break.sh

# Aerc has a bloody nuisance of a bug for an otherwise great email client
# Put this command in your .vimrc, this will let you use the "FA" (Fix Aerc) command
# The FA command will replace all SINGLE line breaks with a space
# As you use double line breaks in your own writing this won't cause problems.
# It will ignore lines that end with commas or full stops.
# It also ignores lines starting with a triangular bracket

:command FA %s/\([^\n,\.]\)\n\([^\n\>]\)/\1 \2/
