Hanging issue when calltip/AutoComplete API file contains many newlines "
"

[rtetsoacrsf]

Description of the Issue

Opening NPP or switching tabs to a python file causes NPP to hang if the 'plugins\APIs\python.xml' file has many newlines ' '. If we replace the with a not formatting string there is no haning however it isn't possible to see all of the calltip.

Steps to Reproduce the Issue

1. Download the attachment python.xml.txt
2. Rename it as "python.xml"
3. Load the python.xml file into plugins\APIs (I suggest backing up the original)
4. Use the language formatting for python either by opening a .py file OR selecting Language --> P --> Python
   (regardless of whether Autocomplete or parameter hints are enabled)

Expected Behavior

There to be no difference in loading time when the calltips contains many newlines

Actual Behavior

There is a massive delay when loading calltip files that have many newlines

Oops, I forgot to include a copy of the python.xml with no newlines.
This is the same file where has been replaced with a representative non-formatting sequence
python.xml with no newlines.txt

Last note:
To see the difference between the formatted and unformatted calltip type:
difflib(
into a python formated file (as in step 4.)
with each plugins\APIs\python.xml file loaded, one will extend of most screens the other will have several newlines in it.
Ensure: Settings --> Preferences... --> auto-completion --> Function parameter hints on input --> enabled
