Subject: Regex returning less number of groups - where is the error?

Hello!

I'm trying to build a regex to count the number of modified files by
commit. For example, for the following svn log output:

------------------------------------------------------------------------
r727998 | bentmann | 2008-12-19 21:50:48 +1100 (Fri, 19 Dec 2008) | 4
lines
Changed paths:
   A
/maven/components/branches/maven-2.0.x/maven-core/src/main/resources/org/apache/maven/messages/messages_de.properties
   M
/maven/components/branches/maven-2.0.x/maven-core/src/main/resources/org/apache/maven/messages/messages_en.properties

[MNG-1830] use ISO 8601 format (not combined for readability)

------------------------------------------------------------------------

It need to return the revision number and the number of modified files,
so the result of match would be something like :

Result 1:
     1. r727871 | brett | 2008-12-19 11:48:07 +1100 (Fri, 19 Dec 2008) |

     2. A
/maven/components/branches/maven-2.0.x/maven-core/src/main/resources/org/apache/maven/messages/messages_de.properties
     3. M
/maven/components/branches/maven-2.0.x/maven-core/src/main/resources/org/apache/maven/messages/messages_en.properties"]
Result 2:
    1. r727871 | brett | 2008-12-19 11:48:07 +1100 (Fri, 19 Dec 2008) |
2 lines
     2. M /maven/components/branches/maven-2.0.x
     3. M
/maven/components/branches/maven-2.0.x/maven-core/src/main/java/org/apache/maven/cli/MavenCli.java

I tried many variations of the following regular expression:

/(^r\d+.*?)(?:^Changed paths:\n)(^\s*[MDA]\s(?:\/[\w.-]+)+/m

but either it returns incomplete results, as:

Result 1

1. r727998 | bentmann | 2008-12-19 21:50:48 +1100 (Fri, 19 Dec 2008) | 4
lines
2. A
/maven/components/branches/maven-2.0.x/maven-core/src/main/resources/org/apache/maven/messages/messages_de.properties

Result 2

1. r727871 | brett | 2008-12-19 11:48:07 +1100 (Fri, 19 Dec 2008) | 2
lines
2. M /maven/components/branches/maven-2.0.x

Would someone be able to help me on this? Thanks in advance!!
