Kurtis Rader	ea45541d53	fix set --show of semi-empty var ... A semi-empty var is one with a single empty string element. The `env_var_t::empty()` method returns true for such vars but we want `set --show` to report that it has a single empty element.	2017-08-16 13:39:48 -07:00
Kurtis Rader	cddc4cfb1d	fix set --show output ... I realized I was printing individual var entries using zero based indexing (like C++) when the indexes should be one based.	2017-08-04 17:08:25 -07:00
Kurtis Rader	7619e62b70	use new logmsg and set --show in tests ... Also modify `logmsg` to output additional separator lines to make the demarcation between tests even clearer.	2017-08-03 21:25:20 -07:00

Kurtis Rader	4197420f39	implement limits on command substitution output ... This makes command substitutions impose the same limit on the amount of data they accept as the `read` builtin. It does not limit output of external commands or builtins in other contexts. Fixes #3822	2017-08-03 17:40:25 -07:00
