Thx.

Why should it be an internal variable?  Did you check how it is used?

Huh?  This is the longest line (but the mailer will perhaps wrap it):

 `start-process' directly, since it offers more control and does not impose

This is the second longest:

 In an interactive call, the variable `shell-command-default-error-buffer'

This the third longest:

 insert output in current buffer.  (This cannot be done asynchronously.)

None of those involves a symbol whose name is 68 or more chars.
They can all be shortened to 70 chars or less.

(All the other lines are 70 chars or less.)
