patch 8.1.1989: the evalfunc.c file is still too big
Commit: https://github.com/vim/vim/commit/af7645d3733fdd3cd2df03ec7b653601d26969ef

patch 8.1.1989: the evalfunc.c file is still too big
Problem: The evalfunc.c file is still too big.
Solution: Move f_pathshorten() to filepath.c. Move f_cscope_connection() to
if_cscope.c. Move diff_ functions to diff.c. Move timer_
functions to ex_cmds2.c. move callback functions to evalvars.c.

| 6 * The basic idea/structure of cscope for Vim was borrowed from Nvi. There | |

1618 * Convert the cscope output into a ctags style entry (as might be found |
| 7 | 1619 * in a ctags tags file). there's one catch though: cscope doesn't tell you |
| 1620 * the type of the tag you are looking for. for example, in Darren Hiebert's | |
| 1621 * ctags (the one that comes with vim), #define's use a line number to find the | |
