-* Quoting.
-
- * Arguments are delimited by white space, which is either a space or a tab.
- * A string surrounded by double quotation marks is interpreted as a single
- argument.
- * A double quotation mark preceded by a backslash, \", is interpreted as a
- literal double quotation mark.
- * Backslashes are interpreted literally, unless they immediately precede a
- double quotation mark.
- * If an even number of backslashes is followed by a double quotation mark,
- then one backslash (\) is placed in the argv array for every pair of
- backslashes (\\), and the double quotation mark (") is interpreted as a
- string delimiter.
- * If an odd number of backslashes is followed by a double quotation mark,
- then one backslash (\) is placed in the argv array for every pair of
- backslashes (\\) and the double quotation mark is interpreted as an escape
- sequence by the remaining backslash, causing a literal double quotation
- mark (") to be placed in argv.
- * In double quote mark need surround such chars:
- & < > [ ] { } ^ = ; ! ' + , ` ~ %
- Also all this char can be escaped by ^ char.
- * Long line can be truncated by ^ char, in this case trailing white spaces
- not allowed.
- * To quote percent sign % before alpha char in batch file double it
- occurrences or plase in quotes:
- prog '%'HOME'%' "%"HOME"%" %%HOME%
