Unexpected addition of a space between operator and sign

[JEAYNE]

Hi,

I'm using Uncrustify-0.78.1_f (downloaded from Github), with Windows 11.
In the examples below I'm using an empty configuration.

1. When I submit this kind of code to uncrustify
   a=b<op>c;
   the output is the same as the input.
   This is true for <op> in { + - * / % << >> | & ^ }
   Example Input:
   a=b/c;
   Output:
   a=b/c;

2. When I submit this kind of code (with <op> != <sign>) to uncrustify
   a=b<op><sign>c;
   the output is
   a=b<op><space><sign>c;
   The addition of this space is true for all combinations where <op> is in { + - * / << >> % | & } and <sign> in { + - } and <op> != <sign>
   EXCEPTION: with operator ^ no space is added between ^ and the sign (input == output )
   Example Input:
   a=b/-c;
   Output:
   a=b/ -c;

Attached a .tar.gz file with the outputs generated by this command
uncrustify -c empty.cfg -f FILE.cpp -L A 2>FILE.log 1>FILE.out
With these 3 input FILEs

• div.cpp is a=b/-c;
• and.cpp is a=b&-c;
• xor.cpp is a=b^-c;
