forge fmt

Operating System

Linux

Describe the bug

forge fmt leaves all .sol files without the newline at the end. This makes them non-conformant with POSIX definition of lines of text. It also conflicts with many tools like text editors, which automatically insert the newline at the end of each file. Various code displaying tools like gitk also treat lack of the newline as an anomaly which needs to be explicitly highlighted, which generates noise.

interesting - cc @rkrasiuk , should we maybe make this on by default and strip if specified in cfg?

[rkrasiuk]

hmm, this looks like a regression. it was addressed in #2177

[gakonst]

fixed in #2690
