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".)

* This function provides a simple assertion function for JavaScript.
|
|
* If the condition is true, this function will do nothing. If the
|
|
* condition is false, then the message will be printed to the console
|
|
* and an alert will appear showing a stack trace, so that the (alpha
|
|
* or nightly) user can file a bug containing it. For future enhancements,
|
|
* see bugs 330077 and 330078.
|

* To suppress the dialogs, you can run with the environment variable
|
|
* XUL_ASSERT_PROMPT set to 0 (if unset, this defaults to 1).
|

|
* @param condition represents the condition that we're asserting to be
|

* true when we call this function--should be
|
|
* something that can be evaluated as a boolean.
|

* @param message a string to be displayed upon failure of the assertion
