Item6849: Search summary broken if TWiki variable spans more than one line

You are not authenticated.

Above IF spans 4 lines. Here is a SEARCH that shows the summary of this topic:

   * Summary in single quotes: 'Test case: Above IF spans 4 lines. Here is a SEARCH that shows the summary of this topic: Special characters do not get filtered out, resulting in broken RSS feeds...'

Special characters do not get filtered out, resulting in broken RSS feeds and broken recent changes with link title based on summary such as WebChangesRightBox

Current output:

• Summary in single quotes: 'Test case: %IF{ "$ LOGIN ! '' AND NOT context authenticated" then 'You are not authenticated.' else 'You are .' }% Above IF spans 4 lines. Here is a SEARCH that ...'

Expected output:

• Summary in single quotes: 'Test case: Above IF spans 4 lines. Here is a SEARCH that shows the summary of this topic: Special characters do not ...'

Fixed:

• $summary() with variables spanning multiple lines
• $summary() with nested variables spanning multiple lines
• $summary(showvarnames) with variables spanning multiple lines
• $summary(showvarnames) with nested variables spanning multiple lines
• quotes (" and ') are now converted to backquotes (`) so that they do not interfere if summery is used in html tag attributes
