parsecfg stores "\r\n" line breaks just as "\n"

[simonkrauter]

When you store a string with Windows line breaks, it just writes "\n" line breaks to the config file.
This is a problem, when the application stores and reads strings and needs Windows compatible line breaks for further usage.

Example

import parsecfg

var cfg = newConfig()
cfg.setSectionkey("Sec1", "Key1", "a\r\nb")
cfg.writeConfig("test.cfg")

cfg = loadConfig("test.cfg")

doAssert cfg.getSectionvalue("Sec1", "Key1") == "a\r\nb"

Current Output

Error: unhandled exception.

File contents:

[Sec1]
Key1="a\nb"

Expected Output

No exception.

File contents:

[Sec1]
Key1="a\r\nb"

Cosmetic issue: What is better: "\r\n" or "\c\l"?
