@brief Dump an M-text.
The mdebug_dump_mtext () function prints the M-text $MT in a human
- readable way to the stderr. $INDENT specifies how many columns to
- indent the lines but the first one. If $FULLP is zero, this
+ readable way to the stderr or to what specified by the environment
+ variable MDEBUG_OUTPUT_FILE. $INDENT specifies how many columns
+ to indent the lines but the first one. If $FULLP is zero, this
function prints only a character code sequence. Otherwise, it
prints the internal byte sequence and text properties as well.
