fix nim secret dots interfering with prompt

[timotheecour]

fixes what #16478 was attempting to fix

after PR:

XDG_CONFIG_HOME= $nimb secret
Hint: used config file '/Users/timothee/git_clone/nim/Nim_prs/config/nim.cfg' [Conf]
Hint: used config file '/Users/timothee/git_clone/nim/Nim_prs/config/config.nims' [Conf]
.....
>>> discard
>>> echo 1
1
>>> import strutils
.........
>>>

and doesn't have the issues mentioned in #16478 (comment)

• change the [Processing] messages into dots #14418 which introduced dots
• compile time echo steals newline from stderr so it's included in stdout instead #16334 which is an issue caused by dots that was recently fixed, see fix #16334 #16335

This maybe solves it for nim secret, but it is not the only instance where the stuff is printed on the same line as dots.

Here is the minimal example:

static:
  echo "same line as dots"
