Change Description

Handles whitespaces in between FPrime access modifiers and the colon, such as PRIVATE:. This will also catch newlines, so patterns like

PRIVATE
:

which are technically correct are handled and formatted correctly.

Note: the output of the formatting tool is not being altered. That is, a PRIVATE : input will result in a PRIVATE: output, which is the correct formatting.

Rationale

Fixes nasa/fprime#1939
