[bug #36831] single character swallowed in output

[Robert Flack]

Follow-up Comment #2, bug #36831 (project grep):

Looking into this, it's definitely the same problem. When grep is in color
mode it outputs the control sequence

unmatched text ^[[01;31m^[[Kmatched text^[[m^[[K^M

If the matched text goes to the end of line, by the vt100 spec the cursor
remains at the end of line on the last character. This means the subsequent
^[[K (erase from cursor to end of line) erases the last character of the
matched text. This depends on the terminal, gnome-terminal and konsole treat
the erase to end of line differently after writing the last character on the
current line.

Does anyone know why the erase to end of line is necessary, given when in no
color mode grep just prints "unmatched text matched text^M" with no erase
codes? Removing these should fix the problem on all terminals.
