Tab size in github source view easily fixed

[BsAtHome]

Tabs in the source are by default interpreted as a distance of 8 spaces. The LinuxCNC code base uses a 4 spaces indentation and there are many files that use a combination of spaces and tabs. This leads to bad indentation in the view,both in github source view and in user's editor.

A very simple solution, without re-indenting the entire source-tree, is to add this little line at the bottom of C/C++ sources and headers:

// vim: ts=4 sw=4

It sets the tabsize (ts) to 4 and the shiftwidth (sw) to 4 (used for < and > commands in vim).

Github knows how to interpret that and anybody who uses a sane editor (sorry for the flame^(*)) will also see everything as it should be.

I think github uses a tab size of 4 characters, whereas in linuxcnc code, 8 characters are assumed (with exceptions like here https://github.com/LinuxCNC/linuxcnc/blob/master/src/emc/task/emctaskmain.cc#L486, that seems to assume tab = 2 characters)

I think my vim ignores those lines, but if i manually do ": set ts=4", everything begins to look like in github (i.e. no improvement). maybe you mean "ts=8 sw=4" for github?

vscode: use this in settings.json:

    "editor.indentSize": 4,
    "editor.tabSize": 8,
    "editor.detectIndentation": false,
