This patch was autogenerated by my decomponents.py It covers almost every file with the extension js, jsm, html, py, xhtml, or xul. It removes blank lines after removed lines, when the removed lines are preceded by either blank lines or the start of a new block. The "start of a new block" is defined fairly hackily: either the line starts with //, ends with */, ends with {, <![CDATA[, """ or '''. The first two cover comments, the third one covers JS, the fourth covers JS embedded in XUL, and the final two cover JS embedded in Python. This also applies if the removed line was the first line of the file. It covers the pattern matching cases like "var {classes: Cc, interfaces: Ci, utils: Cu, results: Cr} = Components;". It'll remove the entire thing if they are all either Ci, Cr, Cc or Cu, or it will remove the appropriate ones and leave the residue behind. If there's only one behind, then it will turn it into a normal, non-pattern matching variable definition. (For instance, "const { classes: Cc, Constructor: CC, interfaces: Ci, utils: Cu } = Components" becomes "const CC = Components.Constructor".)
