Description of change
Ref: https://github.com/nodejs/node/issues/6911
Remove unnecessary backslash in exec()
option maxBuffer
.
Adjust CSS so that links formatted as code
display a grey background.
Note that the CSS changes do affect DOM elements outside of those explicitly listed, API documents outside of child_process.html. For example, in this screen capture, you can see that TOC items with code
formatting also get the grey background treatment.
