This patch implements DCH (delete character) and ICH (insert
character) commands.
DCH - Delete Character:
"As characters are deleted, the remaining characters between the
cursor and right margin move to the left. Character attributes move
with the characters. The terminal adds blank spaces with no visual
character attributes at the right margin. DCH has no effect outside
the scrolling margins" [1].
ICH - Insert Character:
"The ICH sequence inserts Pn blank characters with the normal
character attribute. The cursor remains at the beginning of the
blank characters. Text between the cursor and right margin moves to
the right. Characters scrolled past the right margin are lost. ICH
has no effect outside the scrolling margins" [2].
Without these commands console is barely usable.
