The solarize script evalss the output of the dircolors(1) but the LS_COLORS variable gets exported in its environmnent, not the calling shell where we actually need it so ls(1) and other programs wiill inherit it. Therefore, the evaluation of the dircolors(1) output is moved to the change_bg() function in the shell, so that the LS_COLORS variable is available to any children of the shell. The reason why I had missed this is that in most systems I have ls aliased to exa, which does not care about LS_COLORS and has its own coloring system. On cygwin, however, exa is not available and I noticed that the colors were missind; and indeed, on systems with exa the colors are also missing if I run ls as \ls.

# In tmux, OSC sequences can be forwarded to the underlying terminal by:

# * Wrapping the sequence with `DCS tmux; <sequence> ST`
|
|
# * Replacing ESC in <sequence> with ESC ESC.
|
|
# Either ST or BEL (\a) can be used to end an OSC sequence. However, tmux
|
|
# requires ST to end its wrapping DCS.
