* t4057-diff-combined-paths.sh: use the $( ... ) construct for command ↵Elia Pinto2014-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | substitution The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character. The patch was generated by: for _f in $(find . -name "*.sh") do sed -i 's@`\(.*\)`@$(\1)@g' ${_f} done and then carefully proof-read.

* tests: add checking that combine-diff emits only correct pathsKirill Smelkov2014-02-24
where "correct paths" stands for paths that are different to all parents. Up until now, we were testing combined diff only on one file, or on several files which were all different (t4038-diff-combined.sh). As recent thinko in "simplify intersect_paths() further" showed, and also, since we are going to rework code for finding paths different to all parents, lets write at least basic tests.
