Fix bugs where log.progressEnabled got out of sync with how gauge kept
track of these things resulting in a progressbar that couldn't be disabled.
v4.0.0
Allow creating log levels that are an empty string or 0.
v3.1.2
Update to gauge@1.6.0 adding support for default values for template
items.
v3.1.1
Update to gauge@1.5.3 to fix to 1.x compatibility when it comes to
when a progress bar is enabled. In 1.x if you didn't have a TTY the
progress bar was never shown. In 2.x it merely defaults to disabled,
but you can enable it explicitly if you still want progress updates.
v3.1.0
Update to gauge@2.5.2:
Updates the signal-exit dependency which fixes an incompatibility with
the node profiler.
Uses externalizes its ansi code generation in console-control-strings
Make the default progress bar include the last line printed, colored as it
would be when printing to a tty.
v3.0.0
Switch to gauge@2.0.0, for better performance, better look.
Set stderr/stdout blocking if they're tty's, so that we can hide a
progress bar going to stderr and then safely print to stdout. Without
this the two can end up overlapping producing confusing and sometimes
corrupted output.
v2.0.0
Make the error event non-fatal so that folks can use it as a prefix.
