Allow control characters inside escape sequences
Taken from vt100 manual programmer: Control characters (codes \0 to \37 inclusive) are specifically excluded from the control sequence syntax, but may be embedded within a control sequence. Embedded control characters are executed as soon as they are encountered by the VT100. The processing of the control sequence then continues with the next character received. --- st.c | 68 +++++++++++++++++++++++++++++++++--------------------------------- 1 file changed, 34 insertions(+), 34 deletions(-)dev
