rename2screenx.patch

Patch:    rename2screenx.patch
Probrem:  Currently, GNU Screen version 4.1 has not been released.
          However, the new development version has a very powerful feature.
          want to try it without changing the current environment.
Solution: changes the binary name to 'screenx'

Subject: [screen-devel] Screen patch for string escape, n and new escapes

Hello everyone.

I would like to submit this very simple patch that allows the n escape
to be qualified with a '0'. In other words, the same behavior as both
the 'c' and 'C' escape.

The patch also includes new escapes: j, k, and K.

j, displays the minutes;
k, displays the hour in 24h format; and
K displays the hour in 12h format.

I have also updated the man page.

While the j, k, and K options seem redundant as both the c and C
escapes display both minutes and hours, I would like to have the
flexibility to be able to give each escape a color attribute.

Israel

screen-statusline-showencoding.patch

Patch:    screen-statusline-showencoding.patch
Probrem:  by default, :info command shows each window encoding.
          but it is inconvenient in a multi encoding environment
          to confirm everytime.
Solution: enable to display encoding information at caption/hardstatus.

Subject: [screen-devel] Statusline showencoding patch

Dear,
    I'm so glad that screen supports the encoding transformation. That's =
really a great function for me to switch between Big5 & UTF-8 environment=
! But sometimes I may be confused "What encoding am I using?". Although, =
I can use "Ctrl-a i" to get the information of current window (including =
the encoding info).  I was wondering if the statusline could show the enc=
oding of current window, so I patch it!

    With this patch, I could add a new parameter "%e" to statusline for s=
howing the encoding of current window. This might not be a good solution,=
 but it does work!

    The following is the patch.
