when TEKEN_CONS25 is configured. Fix this by adding a function to set the flag that enables the fix and always calling this function for syscons. Expand the man page for teken_set_cons25(). This function is not very useful since it can only set but not clear 1 flag. In practice, it is only used when TEKEN_CONS25 is configured and all that does is choose the the default emulation for syscons at compile time.

/**
|
|
* The xterm-256 color map has steps of 0x28 (in the range 0-0xff), except
|
|
* for the first step which is 0x5f. Scale to the range 0-6 by dividing
|
|
* by 0x28 and rounding down. The range of 0-5 cannot represent the
|
|
* larger first step.
|
|
*
|
|
* This table is generated by the follow rules:
|
|
* - if all components are equal, the result is black for (0, 0, 0) and
|
|
* (2, 2, 2), else white; otherwise:
|
|
* - subtract the smallest component from all components
|
|
* - if this gives only one nonzero component, then that is the color
|
|
* - else if one component is 2 or more larger than the other nonzero one,
|
|
* then that component gives the color
|
|
* - else there are 2 nonzero components. The color is that of a small
|
|
* equal mixture of these components (cyan, yellow or magenta). E.g.,
|
|
* (0, 5, 6) (Turquoise2) is a much purer cyan than (0, 2, 3)
|
|
* (DeepSkyBlue4), but we map both to cyan since we can't represent
|
|
* delicate shades of either blue or cyan and blue would be worse.
|
|
* Here it is important that components of 1 never occur. Blue would
|
|
* be twice as large as green in (0, 1, 2).
