Richard Miller 19e4049dcd internal/testenv: check that external 'diff' tool is the GNU version ... TestVerifyUnified in internal/lsp/diff/difftest requires specific behaviour of the 'diff' command which is known to be satisfied by GNU diff. The plan9 'diff' command has no '-u' option, and the illumos 'diff -u' produces output in a different format. Checking specifically for the GNU version in the HasTool function ensures the expected behaviour, and otherwise causes the test to be skipped.
