Modified Files: src/tests/bin/sh: t_expand.sh Log Message: Adjust the tilde expansion test to deal with (very) recent changes to what the shell produces for tilde expansions, when the expansion of the tilde prefix ends with '/' and the character immediately following is another '/' - previously /bin/sh (and most other shells, but not all) retained both slashes, and this test expected that behaviour. No longer, now only one of the two will appear. Adjust the expected test results accordingly, and add an extra loop iteration to make sure this is thoroughly tested (one more tilde expansion value). Also, add two new test cases that test for the new (explicit - though it was always stated this way, but not as explicitly) that if HOME is an empty string (not unset - that remains an unspecified case, as it was) then the expansion of ~ must generate "", and not nothing. The current test was unable to distinguish those two, since it simply looked for characters in the output, so add a new test cases explicitly to test for this particular case. This also means (also previously in the standard, but not as explicitly) that shells are not permitted to decide "The ~ expansion produces an empty string, that is weird, let's generate something else instead" which some shells were doing.
