aa10dccf90 Support colon delimiter in ANSI escape sequences 
# Both should work
    printf "\e[38;5;208mOption 1\e[m\nOption 2" | fzf --ansi
    printf "\e[38:5:208mOption 1\e[m\nOption 2" | fzf --ansi

This change makes ANSI parsing slightly slower.

71d11de7ca [tests] Change tests to output to stdout only with verbose flag 
This hides stdout output unless "go test -v" was run.

5a874ae241 Speed up ANSI code processing (#2368) 
This commit speeds up the parsing/processing of ANSI escape codes by
roughly 7.5x. The speedup is mostly accomplished by replacing the regex
with dedicated parsing logic (nextAnsiEscapeSequence()) and reducing the
number of allocations in extractColor().

#### Benchmarks

21b94d2de5 Make fzf pass go vet 
Add String() methods to types, so they can be printed with %s. Change
some %s format specifiers to %v, when the default string representation
is good enough. In Go 1.10, `go test` triggers a parallel `go vet`. So
this also makes fzf pass `go test`.

The updated regular expression should include not all but most of the
frequently used ANSI sequences. Close #735.
