hintProcessing dots are annoying

[ringabout]

static: echo "1234"
import std/sets
static: echo "3456"

prints

....
1234
......
3456

see https://play.nim-lang.org/#ix=2LU4

workaround:

import std/sets
static: echo "1234"
static: echo "3456"

• you can disable them with --hint:processing:off
• you had the exact same issue with the old form without dots, see XDG_CONFIG_HOME= $nim_120_X c -r -f t11696 which shows

Hint: t11696 [Processing]
1234
Hint: sets [Processing]

except that you just "need to know" that dots must be disablabled via --hint:processing:off which admittedly is not obvious

• most dot hintProcessing interference bugs have been fixed except for 1 case I'm aware of (see fix hintProcessing dots interference with static:echo and hintCC; add tests for nim secret, add tests for hintProcessing, misc other bug fixes #16495, it affects windows when called within execCmdEx, refs hintProcessing dot interference issue on windows ringabout/Nim#15)
• erasable log lines would further improve things but PR not finished yet (Erasable log lines #14438; it works though)

proposal

• introduce a flag --processing:dots|path to control whether to use dots or (as before) path
• make --processing:path honor listFullPaths
• in future, erasable log lines (Erasable log lines #14438) could be controlled via --processing:erasable
