[Bug-teseq] codesets are not shown

[Bruno Haible]

Hi Micah,

Nice tool you created! It even recognizes the xterm color-choice sequences.

Find attached a few snippets from ISO-2022 based encodings. teseq does not
show which codesets are chosen. Example:

$ teseq ISO-2022-CN-EXT-snippet
|Chinese (|
: Esc $ ) A
. SO/^N
|VPND|
. SI/^O
|,|
. SO/^N
|FUM(;0|
. SI/^O
|,|
. SO/^N
|::So|
. SI/^O
|)|
. HT/^I SO/^N
|Dc:C|
. SI/^O LF/^J HT/^I
|GB   -- |
: Esc $ ) A
. SO/^N
|T*Fx|
. SI/^O
|  |
. SO/^N
|?*7"|
. SI/^O LF/^J
: Esc $ ) G
& G1DM4: G1-DESIGNATE MULTIBYTE 94-SET
. SO/^N
|^O|
: Esc $ + I
& G3DM4: G3-DESIGNATE MULTIBYTE 94-SET
: Esc O
& SS3: SINGLE-SHIFT THREE
|7J|
: Esc $ * H
& G2DM4: G2-DESIGNATE MULTIBYTE 94-SET
: Esc N
& SS2: SINGLE-SHIFT TWO
|+j|
. SI/^O LF/^J

It would be nice if it showed, as a comment/annotation, that
  Esc $ ) A  switches G1 to GB2312
  Esc $ ) G  switches G1 to CNS11643 plane 1
  Esc $ + I  switches G3 to CNS11643 plane 3
  Esc $ * H  switches G2 to CNS11643 plane 2
etc.

You find the complete list of associations between escape sequences and
codesets at the official ISO IR registry:
